Slow down! Fuel economy decreases about 1% for each mph over 55. Driving 65 mph vs. 55 miles mph, for example, consumes about 10% more fuel.

Use overdrive and cruise control. Overdrive gears slow engine speeds, saving gasoline and reducing wear. By helping to maintain a constant speed, cruise control reduces gasoline consumption. Use both features only when safe and appropriate.

Combine trips when possible. Your engine runs more efficiently once it's warmed up, so consolidate your errands into one trip vs. making multiple short trips. Stop-and-go driving also burns more gasoline. Avoid driving during rush hour whenever you can.
